Answer:

Perimeter = 86.4 (m)

Step-by-step explanation:

A square (with side x) has an area of 466.56 (m^2)

=> x^2 = 466.56

=> x = sqrt(466.56) = 21.6

=> Perimeter of this square: P = 4(x) = 4(21.6) = 86.4 (m)

Hope this helps!

Andrei [34K]

Answer:

Q1. The estimated sum of the two people are between 40 and 55 years old.

Q2. The first person is between 10 and 15 years older.

Step-by-step explanation:

We are given Age Range's for 2 people. The first question is asking for the sum of the two people's ages. In this case we can just add the two minimum ages together and then the two maximum ages like so,

min: 25 + 15 = 40

max: 35 + 20 = 55

So the estimated sum of the two people are between 40 and 55 years old.

The second question asks how much older the First person is from the Second person. We can calculate this by subtracting both age ranges like so,

min: 25 - 15 = 10

max: 35 - 20 = 15

So the first person is between 10 and 15 years older.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

Hello,

Question:

Keisha solved the following equation:

4x − 2x + 8 = 6(x + 4)

Which step has an incorrect justification? (Make sure to type only the number of the step into the blank: 1, 2, 3, 4 or 5)

Correct Solution:

x − 2x + 8 = 6(x + 4)

4x + −2x + 8 = (6) (x) + (6) (4) (Distribute)

4x + −2x + 8 = 6x + 24

(4x + −2x) + (8) = 6x + 24 (Combine Like Terms)

2x + 8 = 6x + 24

Subtract 6x from both sides.

2x + 8 − 6x = 6x + 24 − 6x

−4x + 8 = 24

Subtract 8 from both sides.

−4x + 8 − 8 = 24 − 8

−4x = 16

-4 x -4 = 16

x = -4

Answer:

Where keisha went wrong was forgeting to subtract 6x to both sides.

Incorrrect step is #3
